Hey @griwodz, i've been trying to build your mentioned branch and run into the issue of DevIL not being found. I have installed vcpkg by cloning the vcpkg repo into popsift folder, bootstrapped it from there. Installed all the necessary dependencies as listed in the README, including DevIL, still it can't seem to find it. Can you tell me what i am doing wrong here? Am i missing an argument that points to the DevIL library?

Hi @Apotrox , I don't actually know anything useful about Windows and vcpkg, I rely on the continuous integration on Github to see if Windows compiles. So I googled for something that may help.

"vcpkg install popsift" works by downloading its portfile.cmake
I believe the current portfile is here: https://github.com/microsoft/vcpkg/tree/6146b482ec13d1d33524e9708ffaaf5b7da5af41/ports/popsift

Section 2 on this web page "https://learn.microsoft.com/en-us/vcpkg/get_started/get-started-packaging?pivots=shell-cmd" explains how you can use portfiles in the local filesystem instead of downloading them from github if you set VCPKG_ROOT.

If that works, you can probably get the right branch.

Google gave a page with some hints: microsoft/vcpkg#1081

This looks as if you can update the portfile:

• Maybe by changing "HEAD_REF develop" to "HEAD_REF dev/cmake-lang-cuda"
• More likely by removing the HEAD_REF line and changing "REF 0.9" to "REF 5c37b81". This string is the last Github commit for the branch dev/cmake-lang-cuda.

I interpret the "issues/1801" page as: You try running vcpck once and it fails, but tells you the SHA512 hash you should be using. The "Getting started" web page says the same thing in section 6: try installing, fail, copy the right hash.
Update the hash, try again, and it should try to compile the PR.

One more ... I cannot see that the vcpkg portfile installs DevIL. See here:
https://github.com/microsoft/vcpkg/blob/6146b482ec13d1d33524e9708ffaaf5b7da5af41/ports/popsift/vcpkg.json
But there is a port of DevIL, it's in the long list of ports on the left side of this page.

Maybe the only thing needed is to add devil to vcpkg.json below the 4 boost dependencies?

@griwodz Holy! Thanks! It built!
Note that i went back to the vcpkg installation in AliceVision Framework and set that one as root again (just how it is described in the installation guide).
For future reference, try to build popsift with vcpkg first and have it fail. Then navigate to .\vcpkg\ports\popsift\ and edit the following files:

• portfile.cmake => remove all patches, the HEAD_REF and set REF to the commit desired (as you described).
• vcpkg.json => add devil to dependencies. Maybe increase the port-version, i did that so i can't say if it holds any relevance.
  Then try to build again. It will fail but will give you the new SHA512 hash. Edit the portfile.cmake once again and replace the hash. Done!
